A rack includes a rear wall and two side walls hinged to the rear wall to pivot toward one another when the rack is being collapsed. The side walls include brackets releasably supporting shelves. The shelves are made of metal wire and may be collapsed to a flat configuration and when erected, comprise a rectangular cubic structure. The rear wall has a bottom grid assembly pivotably mounted to the rear wall so that it may be pivoted downwardly when the rack is being opened and assembled, and may be pivoted upwardly to lie flat against the rear wall for storage and transport. The walls are made of a suitable wood or particle board material or lightweight metal.

The invention claimed is: 1. A collapsible rack comprising: a) a rear wall having two opposed side edges, each side edge having a side wall pivotably mounted thereto, each side wall being pivotable between a first position substantially parallel to said rear wall and a second position substantially orthogonal to said rear wall; b) locking means selectively movable to a first position for engaging and locking said side walls in said second position thereof and selectively movable to a second position permitting said side walls to be pivoted to said first position thereof; c) at least one bracket on each side wall; and d) shelving releasably retained on said brackets, said shelving comprising a plurality of shelves included in a single module and said shelves made of wire, each shelf comprising a plurality of crossed wires, said module including a first configuration in which said shelves are erected and a second configuration in which said module is substantially flat for easy storage, said shelves pivoting in transforming said module from said first configuration to said second configuration, and vice-versa. 2. The rack of claim 1, wherein said locking means is pivotably mounted adjacent a lower edge of said rear wall and movable between a first position lying flat against said rear wall and a second position substantially orthogonal to said rear wall. 3. The rack of claim 2, wherein said locking means includes side edges, in said second position of said locking means, said side edges thereof engage respective ones of said side walls to lock each of said side walls in said second position thereof. 4. The rack of claim 3, wherein said locking means comprises a bottom grid assembly including a kick plate. 5. The rack of claim 4, wherein said kick plate is pivotably connected to a bottom grid wire such that in said first position of said locking means, said kick plate may be pivoted to lie in a common plane with said bottom grid wire. 6. The rack of claim 5, wherein said rear wall includes a reinforcing grid including a horizontally disposed piece, said bottom grid being pivotably mounted on said piece. 7. The rack of claim 1, wherein said brackets comprise elongated members horizontally fastened to said side walls and including upwardly facing openings sized and configured to releasably receive fastening portions of said brackets. 8. The rack of claim 7, wherein said openings are arcuate. 9. The rack of claim 7, wherein said openings are J-shaped slots. 10. The rack of claim 7, wherein said fastening portions comprise discs fastened to side extensions of said shelves. 11. The rack of claim 10, wherein said side extensions of said shelves comprise wires extending through openings in gripper bars on each side of said shelves. 12. The rack of claim 10, wherein each gripper bar comprises a pair of gripper bar halves clamped about said side extensions of said shelves. 13. The rack of claim 1, wherein said side walls have widths slightly longer than half a width of said rear wall, whereby in said first position of said side walls, they overlap. 14. The rack of claim 1, devoid of fasteners, whereby said rack may be erected and collapsed without use of any tools. 15. The rack of claim 1, further including a header mounted with a graphic channel suspended above said rear wall and adapted to receive advertising copy. 16. A collapsible rack comprising: a) a rear wall having two opposed side edges, each side edge having a side wall pivotably mounted thereto, each side wall being pivotable between a first position substantially parallel to said rear wall and a second position substantially orthogonal to said rear wall; b) locking means selectively movable to a first position for engaging and locking said side walls in said second position thereof and selectively movable to a second position permitting said side walls to be pivoted to said first position thereof, said locking means comprising a bottom grid assembly including a kick plate, said kick plate being pivotably connected to a bottom grid wire such that in said first position of said locking means, said kick plate may be pivoted to lie in a common plane with said bottom grid wire; c) at least one bracket on each side wall; and d) shelving releasably retained on said brackets, said shelving comprising a plurality of shelves included in a single module, said module including a first configuration in which said shelves are erected and a second configuration in which said module is substantially flat for easy storage, said shelves pivoting in transforming said module from said first configuration to said second configuration, and vice-versa. 17. The rack of claim 16, wherein said bottom grid assembly is pivotably mounted adjacent a lower edge of said rear wall and movable between a first position lying flat against said rear wall and a second position substantially orthogonal to said rear wall, and said bottom grid assembly including side edges, in said second position of said bottom grid assembly, said side edges thereof engaging respective ones of said side walls to lock each of said side walls in said second position thereof. 18. The rack of claim 17, wherein said rear wall includes a reinforcing grid including a horizontally disposed piece, said bottom grid assembly being pivotably mounted on said piece. 19. The rack of claim 16, wherein said side walls have widths slightly longer than half a width of said rear wall, whereby in said first position of said side walls, they overlap, said rack being devoid of fasteners, whereby said rack may be erected and collapsed without use of any tools.
